CONSTITUTION: A temp. and humidity adjusting chamber, e.g. dough conditioner for allowing bread dough to ferment therein while adjusting the temp. and humidity to prescribed values, is controlled by a control part 20 with respect to its parts such as a compressor in the cooling part, circulating fans 8 and 12, a heater 10, a humidifying heater 11C. This control is effected based on the output from a temp. sensor 13 and a humidity sensor 14 supplied with input information. More specifically, the control part 20 is provided with a timing circuit 21C for measuring the usage time of the humidity sensor 14, whereby, when the measuring time reaches a preset time, the replacement time of the humidity sensor 14 is displayed on an indicating panel 23. The control part also measures the usage time of a humidifier and when the measuring time reaches a preset time displays its cleaning time.
